There are about 6461 clinical studies being (or have been) conducted in Russian Federation. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
The study should evaluate the biological distribution of [123I]I-DARPIN-Ec1 in patients with lung and ovarian cancer The primary objective are: 1. To assess the distribution of [123I]I-DARPIN-Ec1 in normal tissues and tumors at different time intervals. 2. To evaluate dosimetry of [123I]I-DARPIN-Ec1. 3. To study the safety and tolerability of the drug [123I]I-DARPIN-Ec1 after a single injection in a diagnostic dosage. The secondary objective are: 1. To compare the obtained [123I]I-DARPIN-Ec1 SPECT imaging results with the data of CT and/or MRI and/or ultrasound examination and immunohistochemical (IHC) studies in lung and ovarian cancer patients.
The aim of the study was to explore potential pathways for recovery and adaptation of neural pathways after stroke by examining electrical activity of the brain cortex and cortico-spinal excitability using transcranial magnetic stimulation in people with motor impairment after stroke. Participants in the study performed a simple stimulus-response task with a healthy and a paralysed limb several times at different stages of basic rehabilitation. To compare the data, a group of healthy volunteers took part in a similar experiment. Investigators recorded cortical activity using electroencephalography and muscle activity using electromyography. After the stimulus-response task, investigators also carried out a study using transcranial magnetic stimulation to assess the integrity of corticospinal connections.
The goal of this clinical study is to prove the no less immunogenicity of the Grippol Quadrivalent vaccine compared to the Grippol plus vaccine in children aged 6 months to 5 years (inclusive) for three identical strains of the compared vaccines in terms of the "proportion of vaccinated with seroconversion in paired sera of the hemagglutination inhibition reaction obtained before and after vaccination".
The goal of this clinical study is to evaluate the efficacy and safety of Longidaza®, lyophilizate for preparation of solution for injection, at a dose of 3000 IU compared to placebo in the treatment of adult patients with residual changes in the lungs after COVID-19 infection
The study is planned to evaluate the therapeutic efficacy and safety of XC8, film-coated tablets, in the treatment of dry non-productive cough on the background of acute respiratory infections in children from 6 to 17 years compared with placebo.
The goal of this interventional is to assess advantages of the ultrasound examination of the lungs in the early postoperative period in cardiac surgical patients after heart surgeries requiring cardiopulmonary bypass. Evaluation of pulmonary complications and outcomes during mid-term follow-up, as well as comparison of ultrasound examination and traditional roentgenologic methods (X-ray examination and CT of the chest) will be performed. The main question[s] it aims to answer are: - Is ultrasound examination of the lungs a more specific and sensitive method in identification of early postoperative pulmonary complications after on-pump cardiac surgical procedures, in comparison with traditional X-ray methods. - Does early identification of interstitial pulmonary edema (based on number of visualised B-lines in the early postoperative period), influences mid-term outcomes in this cohort of patients Participants will undergo ultrasound examination of the lungs on postoperative day 1, 3, 5 and 7 after heart surgery. Based on ultrasound findings and degree of interstitial pulmonary edema, medical (diuretics, anti-inflammatory, e.t.c) therapy will be modified. Researchers will compare this group of patients with control group, in which ultrasound examination will be performed in the same time frames, but no changes in medical management based on ultrasound findings will be made to see if timely administered medical therapy, based on ultrasound findings, can significantly improve symptoms, hospital lengths of stay and outcomes of this patients.
Study rationale: to evaluate clinical and prognostic relevance of microvascular dysfunction, coronary flow reserve and cardioprotective effects of iv administration of esmolol in patients with myocardial infarction. First substudy is an open randomized trial evaluating the efficacy and safety of early intravenous administration of esmolol in patients with acute ST-segment elevation myocardial infarction (MI) and relative contraindications to administration of other intravenous β1-adrenergic blocker (metoprolol etс.). Сomparison group will include patients who have not received intravenous β1-adrenergic blocker. Secondary outcome in this substudy is the degree of microvascular obstruction and infarct size according to MRI with gadolinium delayed enhancement. Second substudy examines the quantitative parameters of coronary physiology in patients with MI and multivessel disease. Changes of coronary physiology measurements over time ((iFR, Pd/Pa, FFR, delta FFR, gradient FFR per time unit (dFFR(t)/dt), pullback pressure gradient (PPG)) measured in the infarct-related artery and in non-infarct-related arteries with diameter stenosis of 50-85% immediately after the completion of a primary percutaneous coronary intervention and during a second hospitalization (30-45 days after STEMI) will be evaluated. The comparison changes of coronary physiology over time with presence of an MVO and infarct size determined by MRI. The model of calculating coronary flow reserve (CFR) based on tridimensional reconstruction of coronary arteries and coronary physiology parameters as measured during coronary angiography will be developed. The influence of coronary physiology parameters measured after complete myocardial revascularization by PCI, and derived CFR in patients with MI on long-term clinical outcomes will be evaluated, based on prospective data collection. Primary composite outcome in all substudies will be the sum of adverse cardiac outcomes (congestive heart failure, episodes of recurrent congestive heart failure worsening resulting in hospitalizations, cardiac mortality, MI recurrences, unstable angina, urgent myocardial revascularization) within > 12 months post-infarction. Secondary composite outcome in all substudies is the degree of microvascular obstruction and infarct size evaluated by MRI with gadolinium delayed enhancement.
This pilot phase 2 study evaluate the effectiveness and safety of pembrolizumab and lenvatinib in patients with anaplastic thyroid cancer. Patients with anaplastic thyroid cancer who are treatment-naive (BRAF-negative) and who were previously treated with chemptherapy or targeted therapy are scheduled to undergo pembrolizumab and lenvatinib and evaluate the outcomes according to the primary and secondary endpoints.
This study is a multi-centre, non-interventional, observational, prospective study with retrospective analysis. The main purpose of the study is to describe the rate of CKD diagnosis in patients with AH and CKD markers. This study will include 10 000 adult outpatients with arterial hypertension, who have one or more Chronic Kidney Disease laboratory markers (without recorded CKD diagnosis prior to enrolment) and have no diabetes mellitus or chronic heart failure, who are monitored and treated by cardiologists or internal medicine specialists in approximately 50 outpatient sites in about 20 regions in Russia. This observational study does not provide for any diagnostic and therapeutic procedures other than those used in routine practice.
The study is aimed at assessing the dynamics of changes in biochemical markers of venous wall remodeling (type 1 plasminogen activation inhibitor (PAI-1), fibronectin (fibronectin, FN), vimentin (vimentin, VM), von Willebrand factor (vWF), PECAM-1 (CD31) ) in patients with C2s-C3s varicose veins compared with healthy volunteers while taking Venarus® (diosmin in combination with hesperidin).
